PROTEINS

Proteins in the human body have a wide range of functions which include: Hormones (insulin, testosterone), Muscle Fibers (actin, muasin), Carrier Protein (Oxygen carrying hemoglobin), Structure/ Support (nails/ hair), Enzymes (biological catalyst), Membrane Transport (Na/ K pump), Cell-to-Cell Recognition, Antibodies. Structure Proteins are polymers made up of amino acid subunits bonded together by peptide bonds.…

ORGANIC REACTIONS

To simplify the multitude of possible combinations of reactants, organic reactions fall under specific types. Combustion Substitution Addition Elimination Oxidation/reduction Condensation (dehydration synthesis) Hydrolysis (hydration) Polymerization Another tool to simplify your task of predicting products is to remember that functional groups will always react the same way. e.g. all 1o alcohols will react the same…

BIOLOGICAL MOLECULES

Biological molecules are macromolecules, which basically means they are polymers composed on small repeating units that have been covalently bonded together.  The exception to this is a type of lipid called triacyleglycerides or phospholipids which are relatively large molecules composed of smaller molecules bonded together. Subunits are chemically liked together in the cell by a…

Haber Process

In order to produce as much ammonia as possible several factors need to be considered. The balanced chemical equation for this reaction is: Therefore a manufacturer would want to affect this equilibrium is such a way that the reaction would constantly wanted to shift to the right. The first way this could be achieved is…

Allergic Reactions & Allergies: Causes & Treatment

Allergy is a disorder of the immune system often also referred to as atopy. Allergic reactions occur to normally harmless environmental substances known as allergens; these reactions are acquired, predictable and rapid. Mind allergies can range from hay fever which causes runny nose and itchy eyes, to life-threatening anaphylactic reactions and potentially death. Allergies are…

Ticker Tape lab answers

Introduction   In physics, any increase or decrease in velocity is referred to as acceleration or deceleration. The rate of acceleration is measured in m/s² or km/m/s respectively. The average acceleration of an object can be derived from the formula: Purpose   To identify the correlation between the movement of the cart and the appearance…
